TEMPORARY BINDER.

sheets of which the magazine is composed.

A further object of my invention is to construct a temporary binder sothat the magazines can be readily secured in position, or detached,without inju thereto.

These objects I attain 1n the following manner, reference being had tothe accompanying drawings, in which:

Figure 1, is a perspective view of one form of temporary binder made inaccordance with my invention, showing a magazine in position and two ofthe attaching wires; Fig. 2, is a sectional plan view on the line 2-2,Fig. 3; Fig. 3, is a transverse sectional view on the line 3-3, Fi 2;Fig. 4, is a transverse sectional view illustrating a I'nodifiedconstruction; Flg. 5, 1s a detached perspective view of the st1fl:' backsection to which the wires are secured; Fig. 6, is a detachedperspective view of one of the wires, and Figs. 7, 8, 9 and 10, areviews illustrating modified forms of the wire attaching means.

Referring to the drawings, A is the back of the binder, which may bemade of metal, and is provided with inturned flanges a-a at oppositeedges.

B are the sides of the binder made, in the present instance, of paperboard, and both the sides and the back are covered with cloth; suchcloth forming the hinges b which unite the sides to the back. Curvedfilling pieces a' may be employed at the ends of the back and add to theappearance of the binder.

D is a metal plate bent to conform to the hack of the binder, as shownin Fig. 3.

- The edges of this plate may be sprung under the flanges aa of the backwhen the binder is in course of construction, and at each end of thisplate are ribs or flanges dd, formed by bending over the edges of theplate. Other modes of attaching the plate D to the back A maybeemployed, however. The flanges d do not extend to the back A; therebeing a space between the flanges and the back to allow for theinsertion of the hooked ends of retaining wires (1, as shown in Fig. 2.

The Wires (3 may be made in the manner shown in Fig. 6, and have bodyportions 0; inclined portions 0 and angular portions 0, and are providedat' their extremities with books 0. These hooks are designed and shapedto engage the flanges d of the plate D, as clearly shown in Fig. 2.There are usually several wires for each binder; the number dependingupon the thickness of the magazines or periodicals confined thereby.

The wires are ofsuch a length that they extend beyond the staples i bywhich the leaves of themagazine I are bound and their hooked ends passbetween the folios, pages,

or other sections of the magazine, beyond the staples and engage theflanged plate D, in the manner shown in Fig. 2. By inclining the ends ofthe wire as indicated at a, any pull on the magazine instead ofreleasing it from the binder will tend to hold it tightly in place dueto the fact that any attempt to straighten the wire will cause thehooked portions of the same to be more firmly forced against the flangesof the plate D; in consequence of which the magazine will be rigidlyheld in place. Another feature of my improved structure is that anystraining of the back will tend to more securely hold the plate D to theback and any attempt to flatten the plate will force the edges of thesame more snugly into the grooves of the back.

When it is desired to remove a magazine from the binder, it is onlynecessary to press down upon the wire retaining it, which. will forceone of the hooked ends away from one of the flanges of the plate D and alongitudinal movement of the wire will move the hooked end clear of theplate; leaving the magazine free to be withdrawn. In some instances, itmaybe desirable to employ a flat back instead of a curved back, and thisconstruction I have illustrated in Fig. 4.

While I'have described the back and the holding plate as made of metal,they may be made of other suitable stifi' materlal without departingfrom the essential features of the invention, and in lieuof securing theholdingplate to the back by means of the inturned flanges, these partsmay 'be riveted It will be understood further that the re-,

taining wires ma be made in any of the shapes shown in igs. 7 8, 9 and10, or in any other equivalent shape which includes hooked ends forengagement with the flanges of the plate, and the same are deemed to bewithin the scope of my invention.

I claim:

1. The combination, in a temporary binder, of a back; sides havin hingedconnections with the back; sai back being made of a sheet of metal orother suitable material and having inturned flanges at its edgesextending arallel with the hinge joint; a plate con ned by said flanges;said late being sprung into position whereby it is rigidly held to theback; and means for securing a magazine or other periodical to saidholding plate.

2. The combination in a temporary 'binder, of a back; sides havinghinged con I nections with the back; said back having an overhangingportion at each edge; a metallic plate arranged to engage theoverhanging ortion of the back and having rearwar ly extending flangesat each end, which reinforce the plate; and wires, having hooked ends,engaging the flanges of the plate, said wires passing through the backof a magazine or other periodical.

v3. The combination, in I a temporary binder, of a metallic back havinan inturned flange at each ed e; a meta lic plate 0t such a width as toe confined by, the flanges of thebackwhen sprung into position and to beheld rigidly to the back; said plate having a flange at each end; withwires having hooked ends engaging the plate; said wires being bent adacent their outer ends to cause the hooked portions to be drawn to etherwhen the magazine section is pulle awa from the back.

In testimony w ereof, I have signed my name'to this specification, inthe presence of two subscribing witnesses.
